(Often mistakenly credited with sinking UC-68 on Apr. 5, 1917 in the North Sea
near Schowen, The Netherlands.
However this attack was made against UB-10
which survived the attack.

UC-68 departed Mar. 10, 1917 from Flanders for a ten day patrol but the boat
never returned.
UC-68 was most likely destroyed by her own mines on or
about Mar. 13, 1917 off Start Point in the English Channel.
A wreck located at position 50.19.09N - 03.30.00W is thought to be that of
UC-68 but could be that of UC-49.)

(Sunk Oct. 6, 1918 after engine failure allowed the boat to be driven against
a destroyer at the East Jetty, Immingham Dock, Humberside, England.
There were no casualties and the boat was raised and repaired)

(Was operating with the Q-Ship Malta to trap U-boats, the two ships parted at
20:15 on Aug. 4 and the last contact with C-33 was made at 21:50, thought to
have been mined but, the wreck has never been located)
